Marine protection is driven by the showed negative impacts being found in our condition, for example, species misfortune, living space corruption and changes in biological community works and spotlights on restricting human-made harm marine environments, reestablishing harmed marine biological communities, and saving powerless species.
Human effects on marine biological systems. Human exercises influence marine biological systems because of contamination, overfishing, the presentation of obtrusive species, and fermentation, which all effect on the marine nourishment web and may prompt generally obscure ramifications for the biodiversity and survival of marine living things.
NUMBER ONE "Natural phenomena such as earthquakes, mountain formation, and volcanoes occur at plate boundaries. Mountains are usually formed at what are called convergent plate boundaries, meaning a boundary at which two plates are moving towards one another. This type of boundary eventually results in a collision." NUMBER TWO At what type of boundaries do oceans occur? List a location where an ocean is getting wider today. . "The theory of plate tectonics is nowadays more or less universally accepted by geologists, and I have mentioned the basic idea briefly at the beginning of this class. The basic thought is, that instead of being permanent fixtures of the earth's surface, the continents and ocean basins undergo continuous change. Both are parts of lithosphere plates that move against each other, and in the process new crust is created at midoceanic ridges (spreading centers), and old crust is consumed at convergent plate boundaries (subduction zones)." NUMBER THREE "The Hawaiian Islands were formed by such a hot spot occurring in the middle of the Pacific Plate."
